The highlights of the firefly dryer box:
Temperature can reach 70℃. The PC/ABS/Nylon requires a high temperature to dry the filament but there are a lot of the filament dryer box can't reach more than 65℃. Firefly dryer box can reach 70℃ so it can dry these filaments correctly.
The 8 filament types+2 custom modes. Firefly dryer box provides 8 filament types of usual, user can select the filament mode and then dry it directly. No need to set temperature+time for the filament they select. Even the newbies can start quickly. For the 2 custom modes, users who have experience with filament then they can set the temperature+ time setting. The dryer box can save the last setting automatically.
Smart APP control. Firefly dryer box developed with tuya main chip, user can download tuya smart/smart life app to control the dryer box. Once the dryer box is connected to the internet via WIFI, the user can control it globally of the world.
Hanging Spool Holder Design. Most of the drying boxes on the market use a design that uses bearings to support the filament. It is true that this is a mature solution, but this solution cannot take into account small-sized filaments. For example, when you use 250g filament, this will become a problem. With a hanging spool design then you can put the filament in the firefly dryer box without a problem. Another side, it can prevent the filament spool thermal deformation problem.
RGB Ambient LED. Firefly is designed with RGB ambient light, you can control the RGB color through touch or APP, making your 3D printing full of fun, and more practically, you can observe the condition of the filament through the ambient light at night.

Q1: Is the dryer box compatible with 250g and 500g filaments?
▼Answer
A1: Yes. It supports all filament spools with 72mm within 1kg.
Q2: Why does the LCD show that the humidity is gradually increasing after a few hours of drying?
▼Answer
A2: The dryer box is not completely sealed to allow moisture to escape. This is normal.
Q3: Why the temperature of my dryer box can't reach 70℃?
▼Answer
A3: Our products have been tested at an ambient temperature of 25℃. If your ambient temperature is lower than 25℃, it may not reach 70℃. You can try wrapping the outside of the drying box with an insulating sponge to reduce heat dissipation and increase the upper-temperature limit (maximum limit is 70℃).
